Based on research, analysis of network data, our ‘snowshoe’ spam detection systems, intelligence sources and our experience, Spamhaus believes that this IP address range is being used or is about to be used for the purpose of high volume ‘snowshoe’ spam emission.
As a precaution therefore we are listing this IP range in an SBL Advisory for the protection of Spamhaus users until we are able to determine the extent of the problem in this IP range, the exact size of the problematic IP allocation within this IP range, who is operating the domains/hosts/servers in this IP range, and receive a reassurance from the network owner that the IP range does not and will not pose a threat to Spamhaus users.
